The talk at Jeremy's Archabbott leads to tri-compounds generally. Gilman's Gutenschach is 3d, continuing G. Smith's concepts in planar pieces 2d and 3d. Gutenschach has a list of its back-rank pieces here that show mono-, bi-, and tri-compounds. Library, for example, is threefold, made of 'Foundation + Theorist + Reporter', defined in Gilman's table, all those options possible a given move. Gutenschach took a lot of work and deserves its first comment now after five-year-old posting. Gutenschach shows more clearly than other 3-d write-ups (on account of the Table) three and more parts in one compounded piece-type obviously apply to higher dimensions than two. Stockbroker is the Pawn analogue and they fill the second rank, ''mov(ing) one step along any of the 9 forward radials,'' with this text noting four restrictions for Stockbrokers. Designers would probably not want to compound Stockbrokers for sake of clarity. Their being nine directions is completely clear, designing three-dimensional Pawn this way: out of any given cube in only one general direction present themselves four vertices, one face, and four edges.
