171 (one hundred [and] seventy-one) is the natural number following 170 and preceding 172.
171 is a triangular number [1] and a Jacobsthal number. [2]
There are 171 transitive relations on three labeled elements, [3] and 171 combinatorially distinct ways of subdividing a cuboid by flat cuts into a mesh of tetrahedra, without adding extra vertices. [4]
The diagonals of a regular decagon meet at 171 points, including both crossings and the vertices of the decagon. [5]
There are 171 faces and edges in the 57-cell, an abstract 4-polytope with hemi- dodecahedral cells that is its own dual polytope. [6]
Within moonshine theory of sporadic groups, the friendly giant is defined as having cyclic groups ⟨ ⟩ that are linked with the function,
This generates 171 moonshine groups within associated with that are principal moduli for different genus zero congruence groups commensurable with the projective linear group . [7]
