all list lengths but has a few extra characters:
mss1=: [: >./ [: (0 >. +)/\. ,&0

Funny, it works ok on my copy of j807 (and is very fast, well done Mike).
It doesn't find the minimum rotation of a vector though, it directly takes a
matrix and returns the nubsieve of the rows, so it expects a rank 2 argument.

I rewrote two explicit and perhaps clearer versions of my sig verb. Both work
on the same principle as the original, but one uses a bit vector and the other
uses a list of indices, and the indices are a bit faster (pun probably
intended). I prefer the bit vector aesthetically though.
Both basic
I like your new version very much Raul. Hard to top that. Hat's off for the
