Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 224

A minimal faithful permutation representation — 4 generators on 23 points:

(2,3,4)(5,7,6)(8,9,12,13)(10,11,14,15)(18,22)(20,23);(1,2,3,5,4,6,7)(9,13)(11,15)(16,17,19,21)(18,20,22,23);(8,10,12,14)(9,11,13,15)(16,18)(17,20)(19,22)(21,23);(8,11)(9,14)(10,13)(12,15)
