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