Grand Staircase of the RMS Titanic the "Olympic", whose B-Deck aft foyer was much smaller because of additional cabins and storage rooms. There was no reception area on the "Olympic" until the 1913 refit, which expanded the restaurant and added a reception area in emulation of "Titanic". On "Titanic" two additional en-suite staterooms were installed off of the A-Deck aft staircase, decreasing the size of the surrounding foyer in comparison to "Olympic". When Robert Ballard discovered the wreck of the "Titanic" in 1985, he found only a gaping well in the place that the Staircase had once occupied. The deck house that once formed the Boat
Titanic prime the prime number theorem. The first discovered titanic primes were the Mersenne primes 2−1 (with 1281 digits), and 2−1 (with 1332 digits). They were both found November 3, 1961, by Alexander Hurwitz. It is a matter of definition which one was discovered first, since the primality of 2−1 was computed first, but Hurwitz saw the computer output about 2−1 first. Samuel Yates called those who proved the primality of a titanic prime "titans". Titanic prime Titanic prime is a term coined by Samuel Yates in the 1980s, denoting a prime number of at least 1000 decimal digits. Few such primes
