For all n≥2,m≥0, every actual named vertex of S(47^n,1^m), including center, every depth 1..47 on each named arm and all original center leaves when present; the selected vertex is the unique zero in a possibly target-specific graceful labeling. The graph has 47n+m edges and the standard graceful label and weight ranges.
假设
S(47^n,1^m) is the finite spider with n named arms of exactly 47 edges and m original unit leaves attached to the center. Graceful means a bijection of vertices to 0..|E| whose absolute edge differences biject to 1..|E|. The labeling can depend on the selected target vertex and has no other zero.
