35 is the number of ways that three things can be selected from a set of seven unique things also known as the "combination of seven things taken three at a time".
35 is a discrete semiprime (or biprime) (5 × 7); the tenth, and the first with 5 as the lowest non-unitary factor. The aliquot sum of 35 is 13 this being the second composite number with such an aliquot sum; the first being the cube 27. 35 is the last member of the first triple cluster of semiprimes 33, 34, 35. The second such triple discrete semiprime cluster is 85, 86, 87.
35 is the highest number one can count to on one's fingers using base 6.
35 is the number of quasigroups of order 4.
35 is the smallest composite number of the form 6k+5, where k is a non-negative integer.
