L.g.f.:A(x)=x+3*x^3/3+5*x^5/5+7*x^7/7+12*x^9/9+11*x^11/11+26*x^13/13+15*x^15/15+51*x ^17/17+19*x^19/19+91*x^21/21+23*x^23/23+155*x^25/25+27*x ^27/27+232*x^29/29+62*x*x^31/31+341*x^33/33+35*x^35/35+592*x^37/37+39*x^39/39+656*x^41/41+344*x^43/43+870*x^45/45+47*x^47/47+1820*x^49/49+51*x^51/51+1431*x^53/53+1441*x^55/55+1843*x^57/57+59*x^59/59+4758*x^61/61+63*x*^63/63+2925*x^65/65+。。。
可以写成
A(x)=x/(1-x^2)+x^9/x ^((2*n-1)^2)/((2*1)*(1-x^(2*n))^(2%n-1))+。。。
当n>=1时,A(x)中的系数x^(2^n+1)/(2^n+1)开始:
[3, 5, 12, 51, 341, 2925, 169033, 33445209, 21619038033, ...,293599英镑(n) ,…]。
