What It Is
Wichmann & Hill (1982) --- three combined short-period LCGs. Python 2's random() engine before Mersenne Twister. Periods ~6.95×10¹²
Interpretation
Standard analysis sees: rich, high-entropy values; aperiodic / broadband; high-complexity (noise-like); monofractal; high-dimensional / space-filling. The atlas detects no named structure beyond this.

What the atlas adds
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
