Odd-homology thickness conjecture for algebraic links with a positive tail

Let pip_i and qjq_j be positive alternating rational tangles, with m2m\ge2, n2n\ge2, and let +k+k denote a sequence of kk pluses, where k1k\ge1. Consider the algebraic link (p1,,pm+k)(q1,,qn)(p_1,\ldots,p_m+k)-(q_1,\ldots,q_n). Let pi\overline p_i and qj\overline q_j denote the reduced tangles and set q=min(q1,,qn)q=\min(\overline q_1,\ldots,\overline q_n).

Positive-tail thickness conjecture. The link is Kh\overline{Kh}'-thick if q>1q>1 and either

min(p1,p2,,pm)>1,k<q,\min(\overline p_1,\overline p_2,\ldots,\overline p_m)>1,\qquad k<q,

or

min(p1,p2,,pm)=1,k+1<q.\min(\overline p_1,\overline p_2,\ldots,\overline p_m)=1,\qquad k+1<q.

This is the next criterion in the paper's computational analysis of algebraic links. The supplied text gives no resolution status.
