I don't know. I'm currently working with Thierry Le Gleuher on
another compilation of problems (soon to come) and i took the
Type A: It is not given who has the move
Type B: The stipulation says who has the move
Type C: One king is in check
Type D: Duplex type B
(Type DD: Duplex type B with same first move)
Type E: Coloring problem
Type F: Coloring problem with one piece or more attacking both kings
But nothing's official. And anyway some more may be lacking, such
as retro-rebuses, etc...

Andrei Frolkine & Andrei Kornilow, without specification.

I think it's an amelioration of 04a (C19 instead of C20),
but with an extra stipulation.
