Presentation

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

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

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