    Since it is possible to find sequences of 36 consecutive integers such that each inner member shares a factor with either the first or the last member, 36 is an ErdÅ‘s–Woods number. [11] The sum of the integers from 1 to 36 is 666 (see number of the beast). 36 is also a Tridecagonal number. [12]

    Thus, the base-36 number WIKI 36 is equal to the senary number 52303230 6. In decimal, it is 1,517,058. The choice of 36 as a radix is convenient in that the digits can be represented using the Arabic numerals 0–9 and the Latin letters A–Z; this choice is the basis of the base36 encoding scheme. The compression effect of 36 being the square ...
