1944_07_01_erdos: Erdős's 1944 theorem that consecutive highly composite numbers lie within a factor 1+(log⁡n)−c1+(\log n)^{-c} of each other, so more than (log⁡x)1+c(\log x)^{1+c} of them lie below xx; it answers the question yes for the exponents k≤1+ck\le1+c.

1971_02_01_nicolas: Nicolas's 1971 upper bound Q(X) = O((log X)^(1+c)) on the number of highly composite numbers up to X, which answers the question no: the count stays below a fixed power of the logarithm.
