There are:
0 digits between the 4 of "4" and the 4 of "40";
1 digit between the 4 of "40" and the 4 of "41";
2 digits between the 4 of "41" and the 4 of "42";
3 digits between the 4 of "42" and the 4 of "43";
4 digits between the 4 of "43" and the 4 of "14";
4 digits between the 4 of "14" and the first 4 of "44";
0 digits between the 4s of "4";
4 digits between the last 4 of "44" and the 4 of "45";
1 digit between the 4 of "45" and the 4 of "46";
5 digits between the 4 of "46" and the 4 of "47";
4 digits between the 4 of "47" and the 4 of "24";
2 digits between the 4 of "24" and the 4 of "47";
etc.
We see that the first column here is the succession of the digits of the sequence, as well as the size of each chunk of digits between two successive 4s.
