128!:3 has width=32 and init=16ffffffff Here's the CRC32 checksum (which has poly 0x04c11db7) using 128!:3:
(#.|.(32#:2)#:016b04c11db7)&(128!:3) That said,, I don't see any examples (starting text, ending checksum) so it would be tedious to determine whether the default 128!:3 polynomial has an exact equivalence.
