Presentation

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

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

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

Polycyclic presentation:

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