Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 3 generators on 21 points:

(1,2,3,5,4)(6,8,9,12)(7,11,10,13)(15,18)(19,21);(7,10)(11,13);(2,3,4,5)(6,7)(8,11)(9,10)(12,13)(14,15,16,19,17,18,20,21)

Polycyclic presentation:

2^6,5|a^2=d,c^2=e,d^2=f,b^a=be,c^a=cf,g^a=g^2,g^d=g^4
