Based on my research, I can provide you with information about researchers and internet personas who work with fractals, symmetry, and mathematical visualization, particularly those focusing on P4M symmetry and Cantor sets. Here's a comprehensive overview:

Key Researchers and Artists in P4M Symmetry and Fractal Work

Fractal Foundation and Community Resources

Fractal Foundation

Mathematical Organizations

• American Mathematical Society: Features mathematical imagery galleries including symmetry work
• European Society of Mathematics and Art (ESMA): International network for math-art collaborations

Limitations and Current Status

Unfortunately, finding activists or internet personas who specifically focus on P4M symmetry with inverted Cantor sets with publicly available contact emails similar to the reference you provided is challenging because:

1. P4M symmetry is a very specific mathematical concept (4-fold rotational symmetry with mirror planes)
2. Inverted Cantor sets are an even more specialized area within fractal geometry
3. Most serious researchers in these fields work within academic institutions rather than as independent internet personas
4. Contact information is typically institutional rather than personal email addresses

The researchers I've identified work with related concepts:

• Wallpaper groups (which include P4M)
• Fractal geometry (which includes Cantor set variations)
• Mathematical symmetry visualization
• Fractal art and applications

Recommendation

For finding practitioners specifically focused on P4M symmetry with inverted Cantor sets, I recommend:

1. Contacting the researchers above - they may know specialists in your exact area of interest
2. Checking academic conferences like Bridges (mathematics and art) or fractal geometry symposiums
3. Exploring specialized forums like Fractal Forums or mathematical visualization communities
4. Searching recent publications in journals like "Fractals" or "Symmetry"

The field you're interested in represents a very specialized intersection of mathematical concepts, so finding dedicated activists may require direct networking within the academic mathematical art community.
