to have a 7digit number < 1 048 000 the first two digits have to stay.
so let's start looking at the third place
1 if we keep the 4, then the remaining digits can be
filled in 5x7x7x7 or 1715 ways
2. If we use a digit other than 4, namely a 0 or 1,
then the remaining digits can be filled in
2x7x7x7x7 or 4802 ways
for a total of 1715+4802 or 6517 ways
systematic list:
