AES always has a blocksize of 128, and a keysize of 128, 192 or 256 bits, because NIST only standardized those modes.

Rijndael on the other hand is more flexible regarding parameters. Wikipedia says:

AES has a fixed block size of 128 bits and a key size of 128, 192, or 256 bits, whereas Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits. The blocksize has a maximum of 256 bits, but the keysize has no theoretical maximum.

136 bits it not a multiple of 32, and thus doesn't work.
