Feb 3, 2022 at 5:19 comment added pajonk @tsh I think this contradicts the nonempty lists contain at least one element with depth 1 condition (the outer list has no elements of depth 1).
Feb 3, 2022 at 5:06 comment added tsh Is [[1]] valid input? As Inv(Inv([[1]])) != [[1]] in current definition.

Feb 2, 2022 at 9:54 comment added Command Master Can we finish a list with a comma? (so the third example would be [[1,],2,[1,],3,[1,],])
