Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 28 points:

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