 A074013 Number of elements of GF(5^n) with trace 1 and subtrace 4. 7
 0, 1, 6, 20, 125, 650, 3025 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,3 COMMENTS Same as the number of elements of GF(5^n) with trace 2 and subtrace 1. Same as the number of elements of GF(5^n) with trace 3 and subtrace 1. Same as the number of elements of GF(5^n) with trace 4 and subtrace 4. LINKS EXAMPLE a(3;3,1)=6. Let GF(5^3) be defined by the field extension GF(5)[x]/( 3+2b+3b^2+b^3 ). The six elements of GF(5^3) with trace 3 and subtrace 1 are { 2+b+b^2, 3+2b+b^2, 4+3b+2b^2, 3+2b+3b^2, 4+3b+4b^2, 4b+4b^2 }. CROSSREFS Cf. A074006, A074007, A074008, A074009, A074010, A074011, A074012.
