I have the following data and want to ount up the number of unique thk + rad combinations.  I should end up with 4 in this example.  How can I do this?

thk      rad1      rad2      rad3      rad4      rad5      rad6
0.118      0.125                              
0.118      0.18      0.136      0.125                  
0.118      0.125                              
0.394      0.125      

If they were not formatted as shown above, we would have this data:
.118 .125
.118 .18
.118 .136
.118 .125
.118 .125
.394 .125
I get 4 unique values here

First, apply an advanced filter (Data>Filter> Select Unique Records Only Checkbox)

Then, use the subtotal function in your summation box. The first argument, 3, lets the subtotal function know that it is giving a "CountA" of all the visible records (database term for row).

I cannot apply a filter to do this.  Not an option.

The functionality of excel when it comes to getting distinct values is relatively limited, out of the box. You could write a short macro for this if you're up to it, unfortunately I'm too busy today. Maybe someone else will write you one. Good luck.

I am assuming that
1) the data is being parsed from some text file and that you can successfully import it such that the rad(x) values are in individual columns
2) there is no distinction between rad1...rad6; they are merely placeholders for "rad" (radius).

I have attached sample VBA code that worked for me with your sample data.  It has a section commented "Import text file" which one could insert code there to import/parse the data as part of the routine, but in this instance, it is processing data already imported and inserted into columns with the labels you described.

Sub UniquePairs()
    Dim cell As Object
    Dim rng As Range
    Dim c, intLastRow As Integer
    Dim strModAdd As String

    ' Import Text File

    ' Convert to Two-column range
    intLastRow = Selection.End(xlDown).Row
    Range("A2", Selection.End(xlDown)).Select
    Set rng = Selection
    For Each cell In rng
        For c = 2 To 6 'check each adjacent column
            If cell.Offset(0, c).Value <> "" Then
                'add value pair to last row
                Range("A" & intLastRow + 1) = cell.Value
                Range("B" & intLastRow + 1) = cell.Offset(0, c).Value
                cell.Offset(0, c).Value = ""
                intLastRow = intLastRow + 1
            End If
        Next c
    Next cell
    Range(Selection, Selection.End(xlDown)).Select
    Range(Selection, Selection.Offset(0, 1)).Select
    strModAdd = Selection.Address
    Range(strModAdd).AdvancedFilter Action:=xlFilterCopy, CopyToRange:=Range("C1" _
        ), Unique:=True
    Range("A:B").EntireColumn.Delete 'optional
End Sub

Here is my version, very similar . . .
Output is put in sheet 2 with a summary (xCounter)

Public Sub FindUniqueRads()
    Dim xRads(2, 1 To 100)
    Dim xArrayPos As Integer
    Dim xFindDup As Integer
    Dim xCounter As Integer
    ' Position in A2
    xArrayPos = 1
    ' Load Values in array
    Do While ActiveCell.Value <> ""
        For xCol = 1 To 6
            ' Skip Empty cells
            If ActiveCell.Offset(0, xCol).Value <> "" Then
                xRads(1, xArrayPos) = ActiveCell.Value
                xRads(2, xArrayPos) = ActiveCell.Offset(0, xCol).Value
                xArrayPos = xArrayPos + 1
                ' Debug.Print xRads(1, xArrayPos), xRads(2, xArrayPos)
            End If
        Next xCol
        ' Jump down one row
        ActiveCell.Offset(1, 0).Select
    ' Remove duplicates
    For idx = UBound(xRads, 2) To LBound(xRads, 2) Step -1
        ' Skip empty elements
        If xRads(1, idx) <> "" Then
            ' Cycle through the rest of the elements and remove duplicate
            For xFindDup = idx - 1 To 1 Step -1
                ' Blank out the Array element if it's a duplicate
                If xRads(1, xFindDup) = xRads(1, idx) And xRads(2, xFindDup) = xRads(2, idx) Then
                    xRads(1, idx) = ""
                    xRads(2, idx) = ""
                End If
            Next xFindDup
            ' If it survived the removal procedure, display
            If xRads(1, idx) <> "" Then
                Debug.Print xRads(1, idx), xRads(2, idx)
            End If
        End If
    Next idx
    ' output if necessary
    xCounter = 0
    For idx = LBound(xRads, 2) To UBound(xRads, 2)
        ' Skip empty elements
        If xRads(1, idx) <> "" Then
            xCounter = xCounter + 1
            ActiveCell.Value = xRads(1, idx)
            ActiveCell.Offset(0, 1).Value = xRads(2, idx)
            Debug.Print xRads(1, idx), xRads(2, idx)
            ' Jump down one row
            ActiveCell.Offset(1, 0).Select
        End If
        Range("E1").Value = xCounter & " unique items found"
    Next idx
End Sub
