Presentation

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

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

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

Polycyclic presentation:

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