• Values of m such that N=(am+1)(bm+1)(cm+1) is a 3-Carmichael number (A087788), where a,b,c = 1,2,25.at n=26A064249
• Values of m such that N = (am+1)(bm+1)(cm+1) is a 3-Carmichael number (A087788), where a,b,c = 1,2,65.at n=10A065700
• Number of integers in n-th generation of tree T(-3/4) defined in Comments.at n=51A274151
• Expansion of 1/(1 - x - Sum_{k>=1} x^prime(k)).at n=19A280917
• Numbers with no 0 digit that are divisible by the sum of any two of their digits at distinct positions.at n=53A308561
• Times on a 12-hour digital clock with 6 digits at which the three continuously moving hands of an analog clock, in the best approximation, enclose the same angles with one another, i.e., have the smallest sum of squares of the deviations from 120 degrees. When interpreting the terms as times of the day in the form hh:mm:ss, padding to the left with zeros is assumed.at n=20A347040
