FACTBOX - Obama's inauguration by the numbers

(Reuters) - U.S. President-elect Barack Obama's historic inauguration in Washington on Tuesday meant crunching a lot of numbers. Here is a snapshot of some of them:

* 5,000: The number of portable toilets to be distributed on the National Mall.

* 10,000: The number of buses that city transportation and Secret Service officials expected to need to ferry people to Washington. Placed end to end, the buses would stretch 85 miles (137 km).

* 240,000: That is how many tickets were distributed, free of charge, for the swearing-in ceremony on Capitol Hill.

* 55: The number of previous presidential inaugurations.

* 1 million: The number of people expected to view the inauguration from the National Mall. Hundreds of thousands more will pack Pennsylvania Avenue to watch the inaugural parade. The record was set during the 1965 inauguration of Lyndon B. Johnson, when 1.2 million people attended.

* $8,249 (5,995 pounds): The price of a seat at the swearing-in ceremony being advertised by one online ticket broker.

* 850: Washington's Metro rail service had that many rail cars, capable of carrying 120,000 people every hour, operating between 4 a.m. and 9 p.m. on the day.

* 8,000: Some 4,000 city police officers were deployed along with 4,000 from 96 other law enforcement agencies across the country.

* 32,000: The total number of military personnel who were on duty or on standby for the inauguration.
