HL75P is an elementary Herschel-to-pi heptomino converter that was found by Chris Cain in May 2015. It consists of a block, two eater 1s, and a pseudo still life containing a transparent block and another still life for a snake-type rock reaction. Shown in the infobox is one of the three block on eater isomers to make the conduit Spartan.

If followed by PF35W and WFx46H, it will yield a conduit that turns a Herschel left in 156 ticks, i.e. an L156. But despite having same rotation, same step, and same repeat time, this conduit and the regular L156 are otherwise unrelated. It can also form Lx129.
