So in the dictionary we see
DET=: 2 : 'v/@,`({."1 u . v $:@minors)@.(0<{:@$) @ ,. "2'
minors=: }."1 @ (1&([\.))
which is as far as I can tell two definitions, for DET and minors.
Is the dictionary meant to say that this DET is used in place
of . when . is used monadically? (And then that DET is defined
in terms of dyadic . , possibly called recursively?
Thanks
