Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

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

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

Polycyclic presentation:

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