%N a(n) is the total number of pentagrams in a variant of pentagram fractal after n iterations.
%C Inspired by A255870. But at the higher iterations, the perimeter would be an irregular polygon instead of a pentagon. The construction rule is vertex to vertex expansion. See illustration in the links.
%H Kival Ngaokrajang, <a href="/A256569/a256569.pdf">Illustration of initial terms</a>
%Y Cf. A255870, A256429, A256571.
