摘要
A "lattice animal" is an edge-connected set of cells on a lattice. In this paper we consider the Tetrakis lattice, and provide the first lower bound on lambda(tau), the growth constant of polyaboloes (animals on this lattice), proving that lambda(tau) >= 2.4345. The proof of the bound is based on a concatenation argument and on calculus manipulations. If we also rely on an unproven assumption, which is, however, supported by empirical data, we obtain the conditional slightly-better lower bound 2.4635.
