 Digit Sequence (Posted on 2005-06-28)
Find the rule and continue this sequence of digits:

1235813941213533488671216141383377554...

Is there a limit to the number of times in a row a digit can appear?

(In reply to First 20,001 digits by Charlie)

That came from

s\$ = "12"
p = 1
DO
t = VAL(MID\$(s\$, p, 1)) + VAL(MID\$(s\$, p + 1, 1))
s\$ = s\$ + LTRIM\$(STR\$(t))
p = p + 1: PRINT p;
LOOP UNTIL LEN(s\$) > 20000
OPEN "longstr.txt" FOR OUTPUT AS #2
DO
PRINT #2, LEFT\$(s\$, 100)
s\$ = MID\$(s\$, 101)
LOOP UNTIL s\$ = ""

CLOSE

111111 occurs beginning at positions 12,463, 13,928 and 17,290.

22222 occurs beginning at positions 16,044 and 17,858.

Added: The first occurrence of 111111 results from a sequence 4747; the other two from sequences of 1010101

The strings of 5 2's come from the strings of 6 1's.
