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