M. Somos discovered around 6200 theta function identities using PARI/GP
scripts without offering the proof. He runs PARI/GP scripts and it works as
a sophisticated programmable calculator. These identities highly resemble
those of Ramanujan?s identities. Here we prove a few theta-function
identities of level 6 discovered by Somos by using modular equations of
degree 3 given by Ramanujan and further we extract some interesting
combinatorial interpretations of colored partitions.
