Presentation

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

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

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