Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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