Octagrammic cupola

In geometry, the octagrammic cupola is a star-cupola made from an octagram, {8/3} and parallel hexadecagram, {16/3}, connected by 8 equilateral triangles and squares.

gollark: You are able to opt out of pinging using the following methods: submersion of your computing device in high-temperature molten rocks exposure of your computing device to cacti and potentially other plants ceasing all interaction with your computing device SCP-[DATA LOST] immersion of your computing device in non-high-temperature non-molten rocks, somehow submersion of your computing device in highly acidic, alkaline or based material exposure of your computing device to large amounts of kinetic energy exposure of your computing device to large amounts of psychic energy exposure of your computing device to vacuum or stellar cores
gollark: > you bastards pinged meIf you don't want to be pinged, cease to exist.
gollark: Yes.
