Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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