Presentation

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

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

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