Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

(2,4)(13,14)(15,18)(16,20)(17,25)(19,22)(21,27)(23,28)(24,26);(5,6,8,10)(7,11,12,9)(13,15,19,16)(14,20,22,18)(17,23,27,24)(21,28,25,26);(1,2,3,4)(5,6)(7,9)(8,10)(11,12)(13,16,19,15)(14,20,22,18)(17,24,27,23)(21,28,25,26);(13,17,19,27)(14,21,22,25)(15,23,16,24)(18,26,20,28);(5,7,8,12)(6,9,10,11)(13,18,19,20)(14,15,22,16)(17,26,27,28)(21,23,25,24)
