Re: Counting
1184 and 1210 are the second smallest pair of amicable numbers. If you add up all the divisors of 1184, including 1 but excluding the number itself, you get 1210; if you add up all the divisors of 1210, including 1 but excluding the number itself, you get 1184:
1 + 2 + 4 + 8 + 16 + 37 + 74 + 148 + 296 + 592 = 1210
1 + 2 + 5 + 10 + 11 + 22 + 55 + 110 + 121 + 242 + 605 = 1184
The smallest pair, 220 and 284, were known to the ancient Greeks, but 1184 and 1210 were overlooked until the 19th century.
1 + 2 + 4 + 8 + 16 + 37 + 74 + 148 + 296 + 592 = 1210
1 + 2 + 5 + 10 + 11 + 22 + 55 + 110 + 121 + 242 + 605 = 1184

1187 – safe prime, Stern prime, balanced prime
A Stern prime, named for Moritz Abraham Stern, is a prime number that is not the sum of a smaller prime and twice the square of a nonzero integer. Or, to put it algebraically, if for a prime q there is no smaller prime p and nonzero integer b such that q = p + 2b², then q is a Stern prime.

If you were watching the skies in 1192, you might have seen Venus pass in front of Jupiter, blocking its light out. (I don't remember it myself - were any other forum members watching?)

In Australia, dialling 1194 gets you the speaking clock.
[Edit for random thought: in the above context, 'dialling' is already archaic.]

In the online guide to Walking Britain, Walk 1195 captures many of the highlights of southern Dovedale in the Peak District National Park. Starting from near Thorpe Cloud, the walk takes the high level route, avoiding the crowds and provides dramatic views across the valley to both Derbyshire and Staffordshire.

Not that you'd see as far as East Lincolnshire. But if you did, you might spot the B1196 running between Alford and Gunby.
