The On-Line Encyclopedia of Integer Sequences (OEIS), also cited simply as Sloane's, is an online database of integer sequences. It was created and maintained by Neil Sloane while a researcher at AT&T Labs. Foreseeing his retirement from AT&T Labs in 2012 and the need for an independent foundation, Sloane agreed to transfer the intellectual property and hosting of the OEIS to the OEIS Foundation in October 2009. Sloane continues to be involved in the OEIS in his role as President of the OEIS Foundation.
OEIS records information on integer sequences of interest to both professional mathematicians and amateurs, and is widely cited. As of 22 August 2015 it contains over 260,000 sequences, making it the largest database of its kind.
Each entry contains the leading terms of the sequence, keywords, mathematical motivations, literature links, and more, including the option to generate a graph or play a musical representation of the sequence. The database is searchable by keyword and by subsequence.
Off with your head
Dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Glitter on the wet streets
Silver over everything
The river's all wet
You're all cold
Dripping with alchemy
Shiver stop shivering
The glitter's all wet
You're all chrome
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
Oh, oh, oh, oh
Off, off with your head
Dance, dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Looking glass, take the past
Shut your eyes, you realize
Looking glass, take the past
Shut your eyes, you realize
Glitter on the wet streets
Silver over everything
The glitter's all wet
You're all chrome, you're all chrome
Oh, oh, oh
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
