The example below compiles with latest ConTeXt, suggesting that the Unicode quadruple symbol ⨌ has not been registered as a math symbol, as the command it is set to is ignored.

You have to extend the entry for ⨌ (0x 2A0C) in char-def.lua to create
the \iiiint command.

Though TeX does not have the \iiiint command, perhaps it should be there, now that Unicode has ⨌. But right now, one cannot assign ⨌ any command.
