What reason did ABC give for the change in actor?q
Precisely : 2E6 , sc ( " q " ) is a covering of 2E6 ( " q " ) , and 2E6 , ad ( " q " ) lies in its automorphism group ; when " q " +1 is not divisible by 3 , all three coincide , and otherwise ( when " q " is congruent to 2 mod 3 ) , the degree of 2E6 , sc ( " q " ) over 2E6 ( " q " ) is 3 and 2E6 ( " q " ) is of index 3 in 2E6 , ad ( " q " ) , which explains why 2E6 , sc ( " q " ) and 2E6 , ad ( " q " ) are often written as 3·2E6 ( " q " ) and 2E6 ( " q " ) ·3 .
