44 (number)

44 (forty-four) is the natural number following 43 and preceding 45.

In mathematics

Forty-four is a repdigit and palindromic number in decimal. It is the fourth happy number, and the fourth octahedral number.

Since the greatest prime factor of 44² + 1 = 1937 is 149 and thus more than 44 twice, 44 is a Størmer number. Given Euler's totient function, φ(44) = 20 and φ(69) = 44.

44 is a tribonacci number, preceded by 7, 13, and 24, whose sum it equals.

44 is the number of derangements of 5 items.

There are 44 distinct stellations of the truncated cube and truncated octahedron, per Miller's rules.

There are forty-four finite simple groups that arise from four general families of such groups:
* Two stem from cyclic groups and alternating groups.
* Sixteen stem from simple groups of Lie type.
* Twenty-six stem from sporadic groups.

Sometimes the Tits group is considered a 17th non-strict simple group of Lie type, or a 27th sporadic group, which would yield a total of 45 finite simple groups.

The friendly giant, which is the largest sporadic group and holds twenty sporadic groups inclusive of itself as subquotients, has at least forty-four conjugacy classes of maximal subgroups.
