Presentation

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

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

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