Oh boy oh boy! I actually know this one. It's an operator called
encode, which looks like a stylized T (you know, in the same way that
the "for every" symbol looks like a stylized inverted A). (The decode
operator, which does the reverse operation, looks like an inverted T.)
I don't know what the equivalent operator is in J, but no doubt there is

Actually, the APL operator takes the list of moduli as the left
I knew that reading that APL book (a language I am almost certain never
to use in the real world in my entire life) last month would pay off!
