Labeled-pile and arbitrary-heap period-two scale invariance conjecture for CIS-Nim

About 14 years old · traced to

Let mm be any positive integer, let FF be a set of positions in mm-heap Nim with labeled piles, and let S⊆RmS\subseteq\mathbb{R}^m be open. For each kk, let π(S,k)\pi(S,k) denote the number of PP-positions of mm-heap Nim−F\mathit{Nim}-F of the form 2kv2^k v with v∈Sv\in S. Labeled-pile and arbitrary-heap period-two scale invariance conjecture. The limit

lim⁡k→∞π(S,k)2(m−1)k\lim_{k\rightarrow\infty}\frac{\pi(S,k)}{2^{(m-1)k}}

converges. This extends the proposed scale invariance from three unlabeled piles to labeled piles and an arbitrary positive number of heaps; the source gives no evidence that it has been resolved.
