Happy Binary Day !
Happy Binary Day !
111110, 62 in decimal.
It is a composite number with the divisors 2 and 31 being the eighteenth discreet semiprime. 62 has an aliquot sum of 34; itself a discrete semiprime, and the 10 member aliquot sequence (62,34,20,22,14,10,8,7,1,0).
Also, 62 is therefore the tenth member of the 7-aliquot tree.
It is a nontotient, and a repdigit in base 5 (222). 62 is also the only number whose cube (238328) consists of 3 digits each occurring 2 times.
Yeah, I don't understand any of that.
