%N Six consecutive integers with increasing values of sigma start at these numbers; i.e., sigma(x) < sigma(x+1) < ... < sigma(x+5).
%C What is the first number to start a run of exactly 5 nondecreasing values of sigma? - _M. F. Hasler_, May 06 2017
%C The first run of exactly 5 nondecreasing values starts at 356067536821, see A285893. - _Giovanni Resta_, May 07 2017
