I think it is more like signposting the neighbourhood for codgers with dodgy memories, Bill...the old bloke with #29 tattooed on the back of his hand will possibly deduce he is somewhere close to home...
Bill Phillips: I must try that, I'll tattoo 38 on the back of mine and hope I never move
Haha! For Dutch wildlife?
I bought three roosting nest pockets from a British shop, made from natural durable materials, I hope the wild birds will accept them as habitat and shelter - but I'm not sure.
Bill Phillips: They would feel at home with this colour Philine. I don't see why the birds shouldn't use them....unless the instructions are only in English
Twenty nine is the tenth prime number, and also the fourth primorial prime. It forms a twin prime pair with thirty-one, which is also a primorial prime. Twenty-nine is also the sixth Sophie Germain prime. It is also the sum of three consecutive squares, 22 + 32 + 42. It is a Lucas prime, a Pell prime, and a tetranacci number. It is an Eisenstein prime with no imaginary part and real part of the form . Since 18! + 1 is a multiple of 29 but 29 is not one more than a multiple 18, 29 is a Pillai prime. 29 is also the 10th supersingular prime.
None of the first 29 natural numbers have more than two different prime factors. This is the longest such consecutive sequence.
29 is the aliquot sum of the odd discrete biprimes 115 and 187 and is the base of the 29-aliquot tree.
29 is a Markov number, appearing in the solutions to : {2, 5, 29}, {2, 29, 169}, {5, 29, 433}, {29, 169, 14701}, etc.
29 is a Perrin number, preceded in the sequence by 12, 17, 22.
Since the greatest prime factor of 292 + 1 = 842 is 421, which is obviously more than 29 twice, 29 is a StÃ¸rmer number.
Bill Phillips: Are you familiar with the expression "I don't give a rat's tiny little ass" ? Well as far as 29 being a prime numbers is concerned I don't. As for the rest of it words fail me. I thought Perrin was one half of the inventor of Worcestershire sauce
I spotted immediately that 29 is a Prime number ... Apart from the obvious characteristic that any prime number has it is important to realise that there is no real logic to primes and no real value. That is aopart from providing research for a PHD.
Now a bird box is actually far more fun ...
Bill Phillips: Typical schoolteacher, but you have redeemed yourself by realising that they serve no useful purpose
