You can have powers of 8 hosts -2. So 2, 4, 8, 16, 32, 64 -2.  So you need a mask for 64 if you have 35 to connect. On a class 2 mask like 192.168.1.0 the mask would be 255.255.255.196.

For a 64-address subnet, you need a 255.255.255.192 mask.  The first (zero host) should not be used, and the last is the broadcast address.

Since you need 35 hosts, you would have to use a /26 subnet [255.255.255.192] - this gives you up to 62 useable hosts, the next one down (/27 subnet [255.255.255.224] ) would have only given you 30 useable hosts

Try this hand table I made (copy and paste into excel)

Decimal Mask            Class A IP Mask      Class B IP Mask      Class C IP Mask      cisco octet       No. Hosts       useable
