Basic Examples

Return OEIS Sequence A000045 (Fibonacci sequence):
[◼]
OEISSequence
["A000045"]
In[]:=
{0,1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597,2584,4181,6765,10946,17711,28657,46368,75025,121393,196418,317811,514229,832040,1346269,2178309,3524578,5702887,9227465,14930352,24157817,39088169,63245986,102334155}
Out[]=

Scope

To get a value of a sequence, index into the produced list:
[◼]
OEISSequence
["A000045"][[5]]
In[]:=
3
Out[]=
OEISSequence returns unevaluated when a sequence does not exist in the OEIS:
[◼]
OEISSequence
["test"]
In[]:=
[◼]
OEISSequence
[test]
Out[]=

Possible Issues

If internet access to the OEIS is not available the function will fail to produce the expected result:
