摘要

For each integer d ≥ 1, let $$begin{array}{ll}fancyscript{F}_d = left{ k in mathbb{Z} : binom{(2^d+1)k}{k} = 1quad ({rm mod};2) right}end{array}$$In this paper we investigate the self-similarity and dimension of each of the sets ({fancyscript{F}_d}) . In particular we show that both the Hausdorff dimension and the packing dimension of ({fancyscript{F}_d}) are ({log ( phi ) /log (2)}) , where ({phi}) is the golden ratio, which demonstrates that ({fancyscript{F}_d}) is a discrete fractal in the sense of Barlow and Taylor (Proc. Lond. Math. Soc. 64:125–152, 1992). Keywords Fractal Hausdorff dimension Packing dimension Binomial coefficients Pascal’s triangle Kummer’s theorem Fibonacci numbers Self-similarity Mathematics Subject Classification (2010) 11B65 28A80 Communicated by K. Schmidt.
