According to subidiom.com the first occurrence of 1984 on Pi is at the 3358th decimal digit. http://www.subidiom.com/pi/pi.asp

enter image description here

I can use the command "3359 digit of pi" to get a similar output on WolframAlpha including nearby digits as you can see below.

Unfortunately it doesn't seem to work with e or phi. Does someone have a workaround for that ?

Thanks,

These appear to work consistently for me

Digits of Pi

Digits of E

Digits of Phi

Nice way to get the sequences on Phi! Do you know if it is possible to look for the first occurrence of a given sequence ? Like "1984", which should be the command to look for the first appearance of this sequence on those constants ? Thank you!

WolframAlpha understands a subset of Mathematica notation. For example it understands this:

Partition[First[RealDigits[Pi,10,100]],4,1]

which gives each subsequent overlapping four tuple of the first 100 digits of Pi in base 10.

What I would then want to do is to find the position of a particular four tuple in that using something like

Position[Partition[First[RealDigits[Pi,10,100]],4,1],{1,5,9,2}]

Unfortunately it appears that the word "Position" somehow confuses this and it is not able to find the position of that four tuple. More unfortunately, I have not been able to find any alternate form of query to accomplish this. But perhaps this might give you or someone else some idea that will lead to a solution.

SequencePosition[First[RealDigits[Pi, 10, 100]], {1, 5, 9, 2}]

Looks like unfortunately it is not working
