Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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