Dear SeqFans,
A002215 Number of polyhexes with n hexagons, having reflectional
symmetry.
Sounds the same as
A030225 Number of n-celled polyhexes (hexagonal polyominoes) with
bilateral symmetry.
Looking at comments, A002215 might be not about all polyhexes but about
restricted or tree-like. I do not know what restricted means, so
someone should suggest the right name for this sequence.
Best, Tanya
