Presentation

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

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

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