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