EXAMPLE

Let u be defined by u(i) = bigomega(3 + 2i). u(i) = 1 for 0 <= i < 3 and u(3) = 2 != 1, and 3 is the smallest such number, hence a(3) = 3.

Let u be defined by u(i) = bigomega(4 + 2i). u(i) = 2 for 0 <= i < 2 and u(3) = 3 != 2 , and 4 is the smallest such number, hence a(2) = 4.

Let u be defined by u(i) = bigomega(151403 + 2i). u(i) = 3 for 0 <= i < 9 and u(9) = 2 != 3, and 151403 is the smallest such number, hence a(9) = 151403.

PROG

(PARI) u(m, i)=bigomega(m+2*i)

card(m)=my(k=u(m, 0), c=0); while(u(m, c)==k, c++); c

a(n)=my(c=0); for(m=1, +oo, c=card(m); if(c==n, return(m)))
