Pyjamask is a light-weight cipher. It has key size of 128 bits, with 14 rounds. It can either have a 96-bit block size value, or a 128-bit one. For the 128-bit block size we have an S-box of:
[2, 13, 3, 9, 7, 11, 10, 6, 14, 0, 15, 4, 8, 5, 1, 12]
For the 96-bit block size, we have a state of 96 bits, 4 bytes in three rows, while the 128-bit block size uses four routes of 4 bytes. More detail [here]
