Mirielle but looking at his example(1326) ,he is considering digits at once and tens place as first 2 digits. If we take that into consideration then there is no possibile answer to this problem.

for i in rang e(10): for j in range(10): for k in range(10): for l in range(10): if l==2*i and j==k and 2*(i*10+j)==k*10+l: print(i,j,k,l) just run this python code
