3c/10 pi wave is a pi wave that travels at 3c/10 orthogonal.

Ever since Martin Gardner's Scientific American column in October 1970, the pi-heptomino has been subject to investigation by many due to its easily recognized forward movement, in which it advances by 9 cells in 30 ticks (hence the speed 9c/30, or simplified to 3c/10). Numerous attempts have been made to remove the hazardous debris left behind and construct a working spaceship, and assembling waves may be a viable route towards that (although no complete construction of this kind are known as of January 2026). The particular pi spacing shown in the infobox was found by Denis Wilson in 1971, which is clean.[1] Other dirty pi waves at this speed were later discovered by Jason Summers.[2]
