6752 - calling Hugo
by Bruce Ure at 16:30 16/09/05 (Blogs::Bruce)
Is there anything special about the number 6752?
I suppose despite being sort of aimed at Hugo this ia open to anyone :)

I've been allocated that number for the Windsor Half Marathon on 25th Sept. Would be nice to find something interesting about it.

Looked for a web site database of interesting numbers but nowt sprang up.

6th July 1952 was the last day that trams ran in London.

or at least until the recent ones in Croydon, ahem.

Well, 6752 = 25 x 211 = 65 - 45 = 2 x (153 + 1) = (2 x 104 + 44)/3.

It's the number of points on the surface of a 5-hypercube of side 5, and on a dodecahedron of side 15.

The partitions of 38 include 6752 8's, and if you inscribe a sphere inside a cube and then divide the cube into a 38 x 38 x 38 lattice, the sphere will intersect the lattice at 6752 points.

1000000000000000000000000000006752 +/- 1 is the first pair of twin primes above 1033.

67522 = 400800415.

(You can find all of this information and more in Sloane's Encyclopaedia of Integer Sequences.)

And continuing Dave's theme in an American style, the actor Liam Neeson was born on 7th June 1952.

Thank you kindly. Exactly the sort of stuff I was looking for. Will consult that site in future.

My fave is "if you inscribe a sphere inside a cube and then divide the cube into a 38 x 38 x 38 lattice, the sphere will intersect the lattice at 6752 points."

Of course, most of my marathon diary readers will know this already, but I shall use it anyway.

Post an entry in last year's Marathon blog pointing at your 2006 version, so that people subscribed to last year's RSS feed get to hear about the new one.
