[edit] In mathematics

111 is a perfect totient number.

111 is R₃ or the second repunit, a number like 11, 111, or 1111 that consists of repeated units, or 1's. It equals 3 × 37, therefore all triplets (numbers like 222 or 777) in base ten are of the form 3n × 37.

All triplets in all bases are multiples of 111 in that base, therefore the number represented by 111 in a particular base is the only triplet that can ever be prime. 111 is not prime in base ten, but is prime in base two, where 111₂ = 7₁₀. It is also prime in these other bases up to 100: 3, 5, 6, 8, 12, 14, 15, 17, 20, 21, 24, 27, 33, 38, 41, 50, 54, 57, 59, 62, 66, 69, 71, 75, 77, 78, 80, 89, 90, and 99. 111 is also prime in base 111 (= 12433₁₀).

The smallest magic square using only 1 and prime numbers has a magic constant of 111:

31	73	7
13	37	61
67	1	43

A six-by-six magic square using the numbers 1 through 36 also has a magic constant of 111:

24	16	33	23	10	5
11	15	28	8	13	36
20	14	2	31	25	19
1	18	6	29	27	30
21	22	7	17	32	12
34	26	35	3	4	91

(The square has this magic constant because 1 + 2 + 3 + ... + 34 + 35 + 36 = 666, and 666 / 6 = 111).

111 is also the magic constant of the n-Queens Problem for n = 6. It is also an enneagonal number.

In base 10, it is a Harshad number and a Zuckerman number.

[edit] Nelson

The number 111 is sometimes called "a Nelson" or "Nelson's" (particularly as a score in cricket or darts) after Admiral Nelson, who allegedly only had "One Eye, One Arm, One Ball" near the end of his life. (This is sometimes bowdlerised to say that he lost "One Eye, One Arm, One Life" during his naval career.) Another suggestion is that the number is derived from his three great victories, thus Copenhagen, Nile and Trafalgar which gives the sequence "Won - Won - Won".^{[citation needed]}

A score of 111 or multiples thereof (called "double nelson", "triple nelson" etc.) is considered an ill omen in cricket, because the figures "111" resemble a wicket without bails. Some people, most notably David Shepherd, practiced superstitions around nelsons.

When any aussie rules scores are G.B = 111 points, and the radio call is on 3AW, the game call team read the score in extravagant voices, led by Rex Hunt, followed by; "LORD NELSON!"
