NAME

Number of free one-sided deltoidal hexecontahedron polykites with n faces.

COMMENTS

The surface of a deltoidal hexecontahedron has 60 congruent faces. Edge-connected faces are called polykites. Reflections are included separately in the counts. Polykites can have from 1 to 60 faces.

Michel Marcus: Let's avoid multi-blanks

Hilarie Orman: In the counts, the rotations of a piece do not contribute to the total, but reflections do contribute.  The Wikipedia definition of "one-sided polyomino" seems to be consistent with this.  I think the correct edit is to say that this sequence counts one-sided polykites and to strike the sentence about reflections.

Andrew Howroyd: I've added the keyword 'fini' (which indicates a sequence is finite). What do you mean by "Reflections are included in the counts"? (previously the wording was Reflections and rotations are not counted separately). Do you mean reflections are counted separately, but rotations not? The normal terminology for polyominos - is 'free', 'one-sided' and 'fixed'. I added 'free' to the name based on your previous description - should it actually be one-sided? (equivalence is up to rotation/translation only)
