I recently discovered many new uniform polytera.

The rat regiment contains a compound of 10 squocts, bic. Now consider the planes that the square bases of each squoct lie on. Each one contains 2 of penteractic symmetry’s 5 tesseractic axes. If we represent each axis with a vertex and connect them with an edge if a square base of a squoct uses both of them, we get a pentachoron graph. Removing half the squocts so that the graph becomes that of a pentagon results in a uniform compound of 5 squocts. This compound can blend with any rat troop that has either opes or tisdips, giving rise to 14 new uniforms. This same construction can also be applied to other compounds of 5 polytopes with the same symmetry as squoct that can be inscribed in a pentic uniform, which should lead to many more uniform polytera.
