A SEQUENCE OF 13's. pro FRI EDITOR OJT TEE "
SPECTATOR."3
Sin,—Your correspondent has failed to notice an additional 13 in his sequence. Not only did the digits of 8,203 total 13, but this number contains 631 times 13. Here is a similar sequence in my own experience. On January 13th, 1913, being then resident at No. 18 Cheniston Gardens, I travelled to Manchester from Euston. My train started from No. 13 platform. I bought an insurance ticket No. 2,704. Here again is a number which totals 13 and is divisible by 13. A sufficiently Curious coincidence of numbers, but consider the sequel-13 days later, January 26th (twice 13), I returned to London. My ticket was numbered in such a way that the four
digits totalled 26 and the whole was divisible by 26. I leave your readers to discover what that number was. Perhaps the difficulty will add to their appreciation of this double coincidence. It only remains to add that I had neither good nor bad luck on either of my journeys.—I am, Sir, Am., GEORGE G. ICEENOCE.
