Heya. Unfortunately I won't be able to maintain the death toll this carnival, so if someone else could do it this year that'd be great.
Fun Fact: "TGM" converted from ASCII to decimal (84 71 77) occurs at the 413786th digit of pi after the decimal point.
This is not necessarily true. There are other "infinite numbers", like 0.333333..., but I guess you do not count that. If we are talking about irrational numbers, for example 0.10110111011110111110... does never repeat, but still does not have "every combination of everything" in it, so it is false that every irrational number has every sequence possible in it.
A irrational number that DOES have every possible combination of the digits from 0 to 10 in it is called a "normal number in base 10". In the case of pi: We do not yet know if pi is a normal number or not. More information: http://mathworld.wolfram.com/NormalNumber.html
