A '''Zeisel number''' is a [[square-free]] [[integer]] ''k'' with at least three [[prime factor]]s which fall into the pattern 

:<math>p_x = ap_{x - 1} + b</math>

where ''a'' and ''b'' are fixed constants and ''x'' is the index number of each prime factor in the factorization, sorted from lowest to highest. For the purpose of determining Zeisel numbers, <math>p_0 = 1</math>. The first few Zeisel numbers are
